AIR-BRAKE GASKET-REPLACING TOOL.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed September 18, 1905. Serial No. 278,886.

To all 1071 0777, it may concern:

Be it known that I, GEORGE citizen of the United States, residing atScranton, in the county of Lackawanna and State of Pennsylvania, haveinvented certain new and useful Improvements in Air- BrakeGasket-Replacing Tools; and I do dea full, clear, and enbeing had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to tools for facilitating repairs to leakyair-brake hose-couplings.

It embodies new and useful improvements in the form of tool coveredbymyPatent No. 787,857, dated April 18, 1905.

Its object is to provide a compact appliance specially adapted to removeold and worn-out rubber packing-gaskets between groove, gasket inposition with the least delay possible and with the least inconvenienceto the train hands. This object I attain by means of the deviceillustrated in the accompanying drawings, where- 1n- Figure 1 representsa general improved gasket-replacing tool. Fig. 2 represents a view ofone member of the familiar form of air-brake hose-coupling, partlybroken away, with the cleaner end of the said tool inserted in the mouthof the coupling for the purposeof scraping out the gasket-groove andFig. 3 represents the coupling with the replacer end of the toolinserted for the purpose of forcing the new gasket home in said groove.

The same letters view of my refer to the same parts where they occur inmore than one view.

Referring now to Fig. 1, A represents the body of the tool, which ispreferably formed of a piece of sheet-steel in the general shape shown.At what I shall call the front end of the tool the metal is cut away, soas to leave the irregular hook-shaped projection or prong B, the end ofwhich is turned up somewhat and brought to a dull cutting edge. C is anelbow-shaped jaw pivoted at D to one face of the body-piece A, and E isa similar jaw pivoted at the same relative point on the other face ofthe said piece. F F and G G are teeth formed on the free end of the jawsO and E. At H there is a wide slot cut out of J. PILGER, a I K, attachedto th the body-piece A, within which play the lugs e jaws C and E,respectively, when the jaws move back and forth.

is a spring pressing against the jaw O in such way as to keep said jawnormally closed. A like spring on the other face of the tool (not shown)keeps the other jaw E closed in the same way. At the back end of thetool the body-piece A is cut away, as shown. M M are rollers shaped witha flange N at their forward end. These rollers are mounted on the longpivots O O and seated a ainst the springs P P, so as to yield and sidealong said pivots under pressure.

Passing to Fig. 2, Q represents one member of an air-brakehose-coupling. Part of the knuckle is broken away in order to show insection the groove R, just within the mouth of the coupling, designedfor the rubber packing-gasket and to illustrate the position of thegasket-replacing tool when the I front end thereof is being used.

Fig. 3 shows a similar view of the coupling with the back end of thetool inserted in the mouth thereof, S being the rubber packinggasket insection.

e various parts of my invention being constructed and arranged asdescribed, its purpose and mode of operation are as follows: With theprong B the old gasket is quickly flipped out. The front end of the toolis then into the mouth of the coupling, as teeth F F G G of pressed intoplace, the teeth G G entering the gasket-groove and F F pressing againstthe face of the coupling. A few turns of the tool back and forth nowsuffices to clean out the groove, and the fact that the jaws O E aremovable enables the tool to adjust itself to couplings varying somewhatin size. The new gasket is now slipped into the groove, and the back endof the tool is applied to the mouth of the cou ling, as shown in Fig. 3.By pressing on t e tool and revolving it the spring-seated rollers M Mpress against the gasket, while the flanges N N force the gasket firmlyand evenly home.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A tool for replacing worn-out gaskets in air-brake hose-couplings,consisting of a bodypiece, a pair of cooperating, oppositelyplaced jawspivoted thereto at the front end and adapted to enter the gasket-groove,and

at the back end a pair of rollers adapted to force the gasket intoplace.

2. A tool for replacing worn-out gaskets in air-brake hose-couplings,consisting of a flat body-piece A, the elbow-shaped cooperating jaws O,E pivoted on opposite faces thereof at its front end, said jaws beingprovided at their free ends with the teeth G, adapted to enter thegasket-groove, and the teeth F, adapted to scrape the face of thecoupling, and at the back end of said body-piece A the cooperatingrollers M; M mounted on the piv ots O and seated against thesprings P,said rollers being shap e l with the flange N at their front end,adapted to press the gasket home, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
